Lead Free Solder material must be used to comply with environmental requirements of new solder joints. Lead Free Solder is available under
the following part numbers :
the following part numbers :
Due to the higher melting point of Lead Free Solder the soldering iron tip temperature needs to be set to 370 degrees centigrade. This requires
soldering equipment capable of accurate temperature control coupled with a good heat recovery characteristics.

Rear Cover Removal
When removing the rear cover it is important to ensure that the top button plate is fixed to the front cabinet and not removed with the rear cover.
This is to avoid breaking the cable connected to the switch button board. It is also important to remember that whilst removing the rear cover it
is kept parallel to the LCD plane.
